VirtualBox Import & Same Mac Address

  • 772

Exported Virtual Box VM (CentOS 5.5 with Guest Additions Installed) - Success
Imported CentOS VM Successfully on another Windows Machine via Windows Batch

Problem :
VM After Import retains the same Mac Address and gets the same IP as it was exported from, is there a way one can either change / flush the IP & MAC while exporting or after Importing ?

a VBoxManage command may be? Which I can put in a batch file after import ?

Will be grateful for your assistance on this Kind Regards

  1. Best Answer

    You can change the macaddress of a machine with

    vboxmanage modifyvm VMName --macaddressN macaddress

    where N is the interface number and macaddress matches the regexp [0-9A-Fa-f][02468ACEace][0-9A-Fa-f]{10}

    eg

    vboxmanage modifyvm VMName --macaddress1 000027D15bE8

    Did you set a static IP address on your base VM ?

    EDIT

    Based on the discussion below I think you will be better off using

    vboxmanage modifyvm VMName --macaddressN auto

    Which will set a new mac address once. The machine will then retain that new mac address.

  2. Here is a simple sample script that I created. It may be useful as an example of what you can do.

    A little side not there are only 8 network interfaces available for configuration

    #!/bin/bash

    # this script changes the network set up $cable a virtual box vim
    vmname="floating"
    nic=1
    hostinterface="eth0"
    cable="off"

    #vboxmanage showvminfo "floating" | grep NIC
    # usefull to see your vms configuration

    ((nic=1))
    echo "network interface $nic"
    vboxmanage modifyvm $vmname --nic$nic bridged --nictype$nic "82540EM" --cableconnected$nic $cable --bridgeadapter$nic $hostinterface --macaddress$nic 08002713F6EA

    ((nic=2))
    echo "network interface $nic"
    vboxmanage modifyvm $vmname --nic$nic bridged --nictype$nic "82540EM" --cableconnected$nic $cable --bridgeadapter$nic $hostinterface --macaddress$nic 08002713F6EB

    vboxmanage showvminfo $vmname | grep NIC
    #vboxmanage startvm "$vmname"
